A Reason to Hate Myself

Most people squash a fly without hesitation. Others ignore the insect, because squashing it takes too much trouble or goes against their principles.
I myself really value these decisions. All practical and moral aspects of squashing a fly must be regarded. It's a long process.
But what's all this worth without decisive action? In the end, I only slightly squash the poor thing and hate myself for the rest of the day.
